Title: Surround sound virtualizer and method with dynamic range compression
Inventor: BROWN CHARLES PHILLIP
IPC: H04S3/00
Filed: 2009-12-01
Abstract: Method and system for generating output signals for reproduction by two physical speakers in response to input audio signals indicative of sound from multiple source locations including at least two rear locations. Typically, the input signals are indicative of sound from three front locations and two rear locations (left and right surround sources). A virtualizer generates left and right surround outputs useful for driving front loudspeakers to emit sound that a listener perceives as emitting from rear sources. Typically, the virtualizer generates left and right surround outputs by transforming rear source inputs in accordance with a head- related transfer function. To ensure that virtual channels are well heard in the presence of other channels, the virtualizer performs dynamic range compression on rear source inputs. The dynamic range compression is preferably accomplished by amplifying rear source inputs or partially processed versions thereof in a nonlinear way relative to front source inputs.

Inventor: VALERO HENRI-PIERRE
IPC: E21B47/00
Filed: 2010-01-05
Abstract: Automatic detection and accurate time picking of weak events embedded in strong noise such as microseismicity induced by hydraulic fracturing is accomplished by: a noise reduction step to separate out the noise and estimate its spectrum; an events detection and confidence indicator step, in which a new statistical test is applied to detect which time windows contain coherent arrivals across components and sensors in the multicomponent array and to indicate the confidence in this detection; and a time-picking step to accurately estimate the time of onset of the arrivals detected above and measure the time delay across the array using a hybrid beamforming method incorporating the use of higher order statistics.    In the context of hydraulic fracturing, this could enhance the coverage and mapping of the fractures while also enabling monitoring from the treatment well itself where there is usually much higher and spatially correlated noise.

The switch has four guides which are located next to one another. The middle two guides, which are rigidly connected to one another, are pivotal about a first axis and the outer two guides, which are connected to one another in an articulated manner, are pivotal about two further axes that are spaced from one another. The switch that is formed by the four guides can thus be pivoted out of a first position into a second position.

Title: Serial-line-scan-encoded multi-color fluorescence microscopy and imaging flow cytometry
Inventor: HENG XIN
IPC: G01N21/00
Filed: 2010-03-18
Abstract: A system for performing high-speed, high-resolution imaging cytometry utilizes a line-scan sensor. A cell to be characterized is transported past a scan region. An optical system focuses an image of a portion of the scan region onto at least one linear light sensor, and repeated readings of light falling on the sensor are taken while a cell is transported though the scan region. The system may image cells directly, or may excite fluorescence in the cells and image the resulting light emitted from the cell by fluorescence.  The system may provide a narrow band of illumination at the scan region. The system may include various filters and imaging optics that enable simultaneous multicolor fluorescence imaging cytometry. Multiple linear sensors may be provided, and images gathered by the individual sensors may be combined to construct an image having improved signal-to--noise characteristics.
